A FITNESS instructor celebrated 40 years of success today (Friday, March 13).

Tom Norton, of Startforth, near Barnard Castle, County Durham, has been leading the Glaxo Keep Fit Club at the GlaxoSmithKline Sports & Social Club since September 1974.

Every Thursday, between 6.30pm and 7.30pm, Mr Norton joins about 15 dedicated gym goers for the class, which is based on cardio vascular exercises.

Mr Norton, 60, said the class, which has not changed in the whole time it has been running, had about 70 regular users at one point.

“The same session has been run for over 40 years just by myself and in 40 years it has not changed and is on the same day and the same time so it’s quite an achievement,” Mr Norton said.
